	Add PPC_QEMU_E500 to corenet_base.config, which is then used to generate corenet64_smp_defconfig and corenet32_smp_defconfig. That then allows both those configs to build kernels that boot in qemu using the ppce500 machine type and respectively -cpu e5500 or -cpu e500mc. The code that is added by PPC_QEMU_E500 just defines another machine with a probe function that recognises qemu, so there should be no change when booting on actual hardware supported by CORENET_GENERIC. The increase in vmlinux size is less than 1KB. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://msgid.link/20230411102838.512859-1-mpe@ellerman.id.au
2019-10-28	powerpc/configs: Rename foo_basic_defconfig to foo_base.config	Michael Ellerman
	We have several "defconfigs" that are not actually full defconfigs they are just a base set of options which are then merged with other fragments to produce a working defconfig. The most obvious example is corenet_basic_defconfig which only contains one symbol CONFIG_CORENET_GENERIC=y. And in fact if you build it as a "defconfig" that one symbol ends up undefined, because its prerequisites are missing. There is also mpc85xx_base_defconfig which doesn't actually enable CONFIG_PPC_85xx. To avoid confusion, rename these config fragments to "foo_base.config" to make it clearer that they are not full defconfigs and are instaed just fragments that are used to generate real defconfigs.
